Famous quotes containing the words surrounding and/or population:
“Formerly, when lying awake at midnight in those woods, I had listened to hear some words or syllables of their language, but it chanced that I listened in vain until I heard the cry of the loon. I have heard it occasionally on the ponds of my native town, but there its wildness is not enhanced by the surrounding scenery.”
—Henry David Thoreau (1817–1862)
“I think that cars today are almost the exact equivalent of the great Gothic cathedrals: I mean the supreme creation of an era, conceived with passion by unknown artists, and consumed in image if not in usage by a whole population which appropriates them as a purely magical object.”
—Roland Barthes (1915–1980)
